Bonus max bet limit on reloads?

Ran into something odd with reload bonus terms lately - trying to figure out if the advertised bonus value is even real when most sites sneak in a tiny max bet cap. Like, they throw you a 50% reload and then quietly limit you to, say, $3 per spin or hand while playing through it. For blackjack, that totally wrecks the edge, right? And on slots, it's like you're stuck grinding forever and the risk/reward drops off a cliff. Feels like these limits practically force you into low-risk, low-reward bets just to even clear the wagering, especially if you're hunting any serious compounding advantage.

Anyone else start to just ignore these reloads unless the max bet is reasonable? Or maybe there's a way to use them to build up a roll without getting trapped in endless grind territory. Curious if someone has managed a decent withdrawal with one of these low max bet reloads or if it's mostly a waste of time for anyone trying to play smart.
